MPN: MPVZ5004G6U ✓ AktifMPVZ5004G6U Ringkasan
What is a piezoresistive pressure sensor? A piezoresistive pressure sensor is a micro-electromechanical (MEMS) device in which implanted strain gauges on a silicon diaphragm change resistance when the diaphragm flexes under pressure; this resistance change is conditioned on-chip into a high-level analog voltage. Within the broader sensor hierarchy, this part sits under board-mount pressure sensors -> MEMS sensors -> sensors -> semiconductors, and is a member of the MPxx5004 family alongside MPXV5004G and MP3V5004 variants.
Key features include an integrated signal conditioner and temperature compensation, 0 to 85 degrees Celsius compensated range, ratiometric analog output that scales with supply voltage, and a fast 1 ms typical response time. The on-chip bipolar signal chain eliminates the need for external amplification, ADC buffering, or software temperature correction, dramatically simplifying host firmware and analog front-end design.
The MPVZ5004G6U uses a vented gauge reference (a top-side vent port exposes the back of the die to ambient atmospheric pressure), which means the device measures pressure relative to local barometric conditions. This is critical for weather-independent absolute measurements and simplifies sealing at the manifold interface.
Typical applications include HVAC variable-air-volume (VAV) controllers, respiratory / sleep-apnea airflow monitoring, altimetry and barometric trend instrumentation, industrial process controllers, and portable weather stations. The wide 5 V single-supply operation makes it a natural fit for 3.3 V / 5 V microcontroller analog input rails.
When designing with this part, place 100 nF + 1 uF decoupling close to the supply pin and route the analog output with a guard trace to keep digital switching noise below the 1 percent FS noise floor. Note that the vented-gauge topology is not suitable for sealed, watertight enclosures without a dedicated vent tube.

Aplikasi Umum
MPVZ5004G6U cocok untuk 6 aplikasis: HVAC Variable Air Volume (VAV) Damper Control, Medical Respiratory / CPAP Airflow Monitoring, Barometric Trend / Weather Station Instrumentation, Industrial Process Differential Pressure Monitoring, Portable Altimeter / Drone Altitude Hold, Smart Home Indoor Air Quality Sensor.
HVAC Variable Air Volume (VAV) Damper Control
The MPVZ5004G6U fits HVAC VAV damper feedback because its 0 to 3.92 kPa span matches the typical 0 to 1 inch water column differential across a damper blade, and the vented gauge reference removes ambient barometric drift from closed-loop airflow control. Used between the duct pickup and a microcontroller ADC, the 1 ms response time is fast enough for proportional-integral damper control loops, and the ratiometric 1 V to 4.9 V output at 5 V scales cleanly with supply tolerance.

Medical Respiratory / CPAP Airflow Monitoring
In CPAP and sleep-apnea airflow circuits, the MPVZ5004G6U's low 3.92 kPa full-scale span and 1 ms response are well-matched to the small differential pressures generated by patient breathing. Placed across a flow restrictor, the analog output can be sampled directly by a battery-powered microcontroller ADC without external amplification. The vented-gauge topology eliminates humidity-induced offset drift that would otherwise corrupt long-duration therapy sessions.

Barometric Trend / Weather Station Instrumentation
Portable weather stations use the MPVZ5004G6U as a low-cost barometric trend sensor with a 1 V to 4.9 V analog output that scales ratiometrically with supply. Because the device is vented to atmosphere, the 0 to 3.92 kPa span is relative to local barometric pressure, ideal for short-term weather-trend delta measurements rather than absolute altimetry. Its 1 ms response is far faster than meteorological time constants, and the 8-SMD module fits compact IoT form factors.

Industrial Process Differential Pressure Monitoring
Factory automation systems use the MPVZ5004G6U to monitor differential pressure across filters, strainers, and pumps where a 0 to 3.92 kPa span covers typical clean-room filter loading. The 0 to 85 degrees Celsius compensated range accommodates most factory-floor environments, and the on-chip calibration eliminates per-unit factory trimming. Routed to a PLC analog input module, the output voltage directly drives setpoint-comparison logic for predictive-maintenance alarms.

Portable Altimeter / Drone Altitude Hold
Consumer drones and handheld altimeters use the MPVZ5004G6U for altitude-hold feedback where the 0 to 3.92 kPa span corresponds to roughly 0 to 400 m above sea level, sufficient for low-altitude precision landings. The 1 ms response time supports rapid climb/descent correction in flight controllers, and the 5 V single-supply operation integrates with standard drone power-distribution boards. The vented-gauge reference requires a vent hole in the enclosure to expose the port to ambient air.

Smart Home Indoor Air Quality Sensor
Smart-home indoor air-quality monitors integrate the MPVZ5004G6U to detect room-pressure changes caused by HVAC operation, window opening, and forced-air ventilation. The 1 V to 4.9 V analog output pairs with a 3.3 V ADC via a simple resistor divider, while the 8-SMD module footprint drops onto standard breakout PCAs. With on-chip temperature compensation and ratiometric output, no firmware-side linearization is required beyond a one-time offset calibration at zero pressure.

- Narrower pressure span for higher resolution in low-pressure applications (vsMPVZ5010GW6U)
- Vented gauge reference for true differential measurement (vsSealed absolute sensors)
Catatan Desain
Place a 100 nF ceramic decoupling capacitor as close as possible to the VDD pin (pin 1) and add a bulk 1 uF to 10 uF tantalum or ceramic cap within 1 cm of the device. The MPVZ5004G6U is a ratiometric analog output sensor, so any ripple or noise on VDD directly couples to VOUT - a clean 5 V rail from an LDO or filtered switching converter is required to maintain specified accuracy over the 1 V to 4.9 V output range.
Route the VOUT trace as a guard-protected analog signal: keep it short, surrounded by GND copper on both sides, and at least 3 mm away from any digital switching traces or switching converter inductors. The 8-SMD module package has a vent port on the top surface - do not seal this port with conformal coating or potting compound, or the gauge reference will be blocked and the sensor will report a static offset that drifts with temperature.
Do not operate the MPVZ5004G6U in a sealed, watertight enclosure without a dedicated vent tube routed to the outside atmosphere. The vented-gauge topology requires continuous exposure of the reference port to ambient barometric pressure; sealing the port will cause the sensor to read the enclosure's internal pressure rather than true atmospheric pressure, producing altitude- and weather-dependent offset errors that cannot be software-corrected.
Add an RC low-pass filter (typically 1 kohm + 100 nF) at the VOUT pin if the host ADC input is noisy or if the application requires sub-millisecond response. Without filtering, high-frequency noise from digital ground bounce or switching regulators can alias into the ADC conversion and degrade the effective pressure resolution below the 1 percent FS datasheet specification.
